A critic is a person who communicates an assessment and an opinion of various forms of creative works such as art, literature, music, cinema, theater, fashion, architecture, and food. Critics may also take as their subject social or government policy. Critical judgments, whether derived from critical thinking or not, weigh up a range of factors, including an assessment of the extent to which the item under review achieves its purpose and its creator's intention and a knowledge of its context. They may also include a positive or negative personal response.

Critical thinking is the analysis of available facts, evidence, observations, and arguments in order to form a judgement by the application of rational, skeptical, and unbiased analyses and evaluation. The application of critical thinking includes self-directed, self-disciplined, self-monitored, and self-corrective habits of the mind, thus a critical thinker is a person who practices the skills of critical thinking or has been trained and educated in its disciplines. Philosopher Richard W. Paul said that the mind of a critical thinker engages the person's intellectual abilities and personality traits. Critical thinking presupposes assent to rigorous standards of excellence and mindful command of their use in effective communication and problem solving, and a commitment to overcome egocentrism and sociocentrism.
